Hello I found a way to do this with the dash.conf file usingNo, there is no way to do this. If you need large denom, eg 10 DASH in size, the way to encourage their formation is to start with a large UTXO for it to denominate, so, if your mixing wallet is filled with dust, create a new address and goto the send tab and send all the DASH to that address and start mixing over. This should create more of the larger denoms and fewer of the dust ones. Good luck!
Now I now longer have 50+ tiny denoms
